<dd><p>Save a hardcopy of the current figure to file (with the given
filename). The file format (image type) is determined from the
extension of the filename. If any changes have been made by working
directly on the backend instance, set the keyword argument replot
to False to stop Easyviz from replotting the current figure and
destroying those changes.
The figure can be stored in either a vector PostScript (PS/EPS) or
PDF file using GL2PS or a image file (PNG/PNM/JPEG/TIFF/BMP) using
a corresponding vtkWriter instance. PostScript output can also be
generated using vtkPostScriptWriter if vector_file is set to False.
TeX output is also available, but only the text output will be saved
to the file.</p>
<p>If the given filename has no extension, then EPS output will be used.</p>
<p>Keyword arguments:</p>
<blockquote>
<div><dl class="docutils">
<dt>quality     &#8211; Sets the quality of the resulting image. Affects only</dt>
<dd>JPEG images. Given as an integer between 0 and 100
where 100 results in the best quality (but also
the largest file). The default is quality=100.</dd>
<dt>progressive &#8211; Sets whether to use progressive JPEG generation or</dt>
<dd>not. Defaults to False.</dd>
<dt>vector_file &#8211; If True (default), the figure will be stored as a</dt>
<dd>vector file. This is only true if either PS, EPS,
or PDF are choosen as the output file format.</dd>
</dl>
</div></blockquote>
<p>Additional keyword arguments (only in affect if the vector_file
argument is set to True and the file format is either PS, EPS or PDF):</p>
<blockquote>
<div><dl class="docutils">
<dt>landscape &#8211; Sets whether to use landscape or portrait orientation.</dt>
<dd>A True value result in landscape orientation. Defaults
to False.</dd>
<dt>raster3d  &#8211; If True, this will write 3D props as raster images</dt>
<dd>while 2D props are rendered using vector graphic
primitives. Defaults to False.</dd>
<dt>compress  &#8211; Compression when generating PostScript or PDF output.</dt>
<dd>The default is False (no compression).</dd>
